Omega General Help / Vibration / slight thud from transmission at motorway speeds

« on: 30 July 2017, 11:19:23 »

Car is ok up to about 70, but above this there is a thudding or vibration from what seems like the gearbox or just downstream.
What could this be?

Changes seem smooth enough.
No fault codes or warnings.

Thanks

Omega General Help / Gearbox shifting problems - fault codes explanation?

« on: 12 May 2017, 14:57:49 »

My 2.2 auto has a gearbox shifting problem, which I have asked about on here before. Most noticably, it sometimes stays in first too long when accelerating. It may not be changing properly at other times.  Having said that it does work, and it seems not to be deteriorating.
Gearbox specialists have been little help - it could be slipping they say, but could this happen with the 2.2?
The fluid is said to be ok, and changing the fluid is expensive, and they don't recommend it (although they have on here).
I have got a sheet of gearbox fault codes - could an OOFer translate them?
Assuming that it did indicate a repair, where could I take it?
Thanks again.

Omega General Help / Familiar topic - leaky V6 rocker covers

« on: 11 May 2017, 19:57:19 »

I know there is a procedure for refitting gaskets to the V6 rocker covers.
If you want a more permanent repair, can the rocker covers be replaced? I am aware of the metal vectra rocker covers.
I think Omega rocker covers are no longer a new spare part (and would be costly). Is it plausible to buy used ones and try them?
The resealing cost is the gaskets  (£90?) plus labour (couple hrs?)
Thanks

Omega General Help / MOT advisory - corrosion near rear seat belt anchorage outer sill?

« on: 28 April 2017, 18:35:07 »

Is this rust area expensive to fix when the time comes?
It is advisory now but am thinking ahead...
Thank you.

General Car Chat / Noticeably more creep

« on: 19 April 2017, 21:00:17 »

My 2.2 auto has noticeably higher creep power than my 2.6, in both directions. What could explain this - is it a fault? It could be, because the 2.2 does have a gearbox fault.
NB I have been advised here to change the fluid and filter, but when asking about this at specialists they have said its not the fluid, or it won't help. The car drives ok.
Thanks.

Omega General Help / 2.6 V6 fuel injector

« on: 06 April 2017, 18:43:46 »

My '02 2.6 V6 developed a misfire on the road, which shows up as cylinder 2 fuel injector and misfire on other cylinders. Originally EML light,  then engine symbol.  Occurs at all lower revs, rough running.  New injector quoted £270.
Seems fairly straightforward, or is there anything else this could be, or that I should do before getting the repair done?
Other than topping up, I haven't done any maintenance to the car yet (only just bought it).
Thank you.

Omega General Help / Mystery shifting or power problem - suggestions?

« on: 11 October 2015, 18:39:28 »

Hello,
I have had my 2.2 auto petrol for some time - has been ok and reliable.  However it has an issue which I would like to sort, but several garages don't know, but it may be a specialist but common issue.  Sorry its a long email, but its a bit of a mystery (so far at least). Thanks.
The most obvious symptom is that it sometimes delays shifting from 1st to 2nd, you have to rev up to 3500 before it goes.  After this its OK. It can do that once or more per journey but not every change up. Garages have checked the common sensors and the gearbox but its not these. There are ECU fault codes, cam sensor and transmission fault code, and transmission fault codes, but these items are mechanically OK, and the cars drives OK apart from the symptoms. The other symptoms are the car doesnt start very reliably, and I've always thought it is down on power- it doesnt pull well up hills, and I think it uses more fuel than it should. The faulty shifting is believed to be because it runs down on power at idle, upsetting the schedules. What things can I ask the garage to look at?

Thanks
Stuart.

Omega General Help / Auto box delayed shift

« on: 25 November 2014, 23:56:50 »

Hello,
New to the forum.
My Omega 2.2 auto seems ok. Changes seem fine most of the time, except after going up a hill and then coming to a halt it seems to stay in first too long. I think this because it revs up to 3-4000rpm. I haven't checked the fluid etc.yet.
Thanks
Stuart.

Newbie Welcome Area / Hello

« on: 25 November 2014, 23:38:51 »

I've thought Omegas were smart cars for a long time, and now I've got one, and joined the forum - hello!
Its a 2.2 CDX auto.
I was a bit worried about buying such an old car to begin with, especially as its a bit lacking history, but it seems OK. It has one or two usual niggles.
One thing I would like to know about if anyone can help is the car has the habit of holding on to first gear for too long when you have just climbed a gentle hill? The changes seem OK otherwise.
Still the smartest cars on the road!
Cheers Stuart.
